The crankarms and timing chain that's on the left side of the bike is supposed to be on the right - along with the captain's cranks:



Someone flipped the front (captain's) cranks, and added an additional right-hand crank arm on the left side.

All you need the shop to do is put the captain's left crankarm on the right side, and vise versa (and possibly flip the bottom bracket around), and find another left-hand arm to put in the back. The shop can re-install the proper rings for the timing chain on the right side.

Do you follow me now? If not, come on down here to Miami (when it warms up!) and bring the tandem with you

Take care,
